Memory Foraging: When the Brain Behaves Like a Bee

One evening, when working late, Mr. Hills found himself suddenly transported in time. He came upon a campfire with what appeared to be humanoids around it. He joined them, ever so quietly and subtly, but got their attention when he began to tell them about his discovery of how foraging for food and memory are similar. Of course, they had no idea what he was saying, since they could only grunt, laugh and cry. At one point as he got excited in trying to convey the gravity of his discovery, they foraged their memories and realized that he seemed similar to something they ate a few months ago... and it was tasty.

I guess this sort of research is applicable to AI., if one can survive the dangers.
